To allwitom it may concern: *Y

Be itknown that'I, ROBERT J. Ennis, a citizen of the United States, residing at Jenny Lind, in the county of Calaveras and Stateof California, have invented certain new and useful- Improvements* in Carbu( rters'; and I do declare the following to 'ne a full, clear, and exact description -of the saine, such as will enable others skilled .inthe art -to which it appertains to make'and f use the same, reference being-had to the,e ac-v companying drawings, and to the characters of reference marked thereon, which. form a part of this-application.

This invention relates to improvements in .carburetersf .used on gas and gasolen'een-y gines 'of all-characters, the-object'of the invention being to produce a device whereby the mixture of air and' gasolene and the gasi" fy'ing of lthe samewill be complete and perfeet; also one in which the air and lgasolene f will be fed intothe carbureter automaticlally and in just the proper quantities accordingto the Saeed o the engine,and circus la'tedthroug the carbureter in such manner as. to thoroughly vaporize the gasolene and mix' it with the air in a proper manner.

' These objects are accomplished by means of a 'caxbureter formed of an'outer and inner.

ixedcasing, inverted one withinthe other, a gasolene chamber at thelover endl of the outer easing, means 'for conveying the gaso lene into said outer-casing, means conveying air into said casi-ng, a mixing mechanism in Vsaid casings; and bysuch other and further constructionas hwillvappear by a perusal of the following specification and claims.

In the drawings similar characters of'reference indicate corresponding parts in-the several views.

Figure 1 is avert-ical section of the im# proved carbureter. 'Fig -2 is a top plan .Jv-iew of the same. 'Fig. 3 is a fragmentary View of .a screw fand sprin adjustment and prlmlng rod.'l Fig. 4 1s a ragmeutary view ofaa valve mechanism.

Referring more particularly to the char- 'near its ,lower'end, the said lower end being lopen. In the top of the cap 2 a nd opening intothe casing 4 are holes 6 over which is -will appear.

On .the rod 24 on each side of the top of f the member.26 are adjustment nuts 29 andi@ -.30,-while 31 is a screw surrounding'the rod 24 and screwedint'o the membe'r2 andhavan inverted 4tube 2G havin' a plurality ofA 3*" ing4 a square shoulder 32 fitted intthe mem-j' 9'5 bel' 7.- Encircling the memberl 4and bear-'4 ing between the. top of .the member 26 `and the under side of the member 2is'a s ring 33.1.9".

The casing 1 is provided with ho es34 lin its sides inrmediate the chamber 16 and f100 plunger 28, all for a purpose aswillapp'ear.`

In practice whcnthe throttle 10 is 'open the suction from the engine draws the-plun ger 28 and incidentally the tube 26, rod24 and diaphragm 20 upward.
